Patent DE-2710254-A1 (DE)
Inventor: WAELTI ROBERT
IPC: B05B16/60
Filed: 1977-03-09
Abstract: In the method, during spraying a part, for example 30 %, of the exhaust air is mixed with the supply air stream and, during the times between spraying, up to 100 % of the exhaust air is used as supply air in the system. Considerable savings in heating costs can be made thereby. The exhaust air flows through coarse filters (52), band filters (51, 52) and, after it leaves a fan (9), is directed by a flap (32) entirely or partly, depending on operating requirements, into a supply air duct (24). Fresh air sucked in by the fan (8) is preheated via a plate heat exchanger (42) around which the exhaust air flows and is heated together with the admixed exhaust air in an air heater (40) in order then to be blown into the work space (1). The position of the flap (32) can be controlled completely automatically by the operation of the spraying device and by the measuring equipment indicating the air composition. The filters (51, 52) replace the scrubbing device used hitherto. <IMAGE>

Inventor: LUESCHER HANS
IPC: G07D1/00
Filed: 1977-05-20
Abstract: The device contains a plurality of coin-stacking tubes (16, 17, 18). Each coin-stacking tube (for example, 18) is assigned a rotatable perforated disc (15) with four holes (30, 31) and a stationary cover plate (22) arranged directly underneath the perforated disc.

Patent DE-2815761-A1 (DE)
Inventor: SCHREIBER PETER
IPC: C25D7/04
Filed: 1978-04-12
Abstract: For the purpose of electroplating the internal surfaces of tubes, the tubes (11) are gripped and sealed by closure heads (23) at their ends.

Title: Single antenna radiating elliptical field - uses semi-luneberg lens and reflecting disc placed in rotationally symmetric field
Inventor: GMEINWIESER WALTER
IPC: H01Q25/00
Filed: 1978-11-15
Abstract: The antenna system uses two-wire spiral antennas having rotationally symmetric field patterns to produce an elliptical field pattern. Each antenna (5) has its axis of symmetry (3) parallel to and above a metal disc (2) which is connected to the lower flat surface of a dielectric semi-Luneberg lens (1). The outside spiral end is connected to the earth of the supply cable and the reflecting metal disc (2). The Luneberg lens consists of a homogeneous foam half-shell whose dielectric constant increases from its surface to its centre. This causes the beam to be focussed in the azimuthal direction and diverged along the elevation. The divergence occurs since the radiation is reflected off the metal disc and is diverged by the lens. This results in a field pattern with an elliptical cross-section.
